摘要：

A series of uniaxial and biaxial cyclic tests with Proportional or nonproportional loading path and with different strain-rate histories are conducted on thin-walled circular cylindrical specimens of type 304 stainless steel. The results of these tests show that once a material is stabilized under a lower strain rate, the stress-strain response is not appreciably affected by a jump to a higher strain rate. A rate-dependent constitutive model recently proposed by ELLYIN and XIA [1991] has been extended to predict the above-mentioned strain-rate history effect. A comparison between the predictions of the extended model and the test results shows that most of the rate-dependent features of the material can be simulated by the model.
